-STREET REcElvER.

SPECIFICATIN forming part of Letters Patent No. 416,830, dated December 10, 1889.

Application filed Tune 7, 1889. Serial No. 313,426. (No model.)

To @ZZ whom t may concern.-

Be it known that I, THOMAS DARK, a citi- 'zen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Street Receivers; and` I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements on my former patents for street receivers, the object being to first overcome diiiiculties when; such receivers are placed instreets that are afterward raised or lowered to conform to anew grade; and, second, to change the shape of the receiver at the back and bottom and set the stench-trap door at such an angle asgto drop the water-with more force into the trap and force `the sand and sedi ment out of the trap into the sewer; and the invention, as constructed, will be understood by reference'to the following specification and claims.

, In the drawings, Figure 1 is a cross-section through the whole device, and showing the` grading; Fig. 2, front elevation of receiver in position; Fig. 8, front cross-section; Fig'. 4, side elevation of whole receiver; Figs. 5 and 6, details of trap-door.

The receiver is made of iron in two parts, the upper section A, in which the grate D sets, and the bottom section A', both slanting from top to bottom. The upper part A sets a few inches inside the lower section A', telescoping therein, and held together, at such @height desired, by bolts a et passing through both, the inside section A having vertical slots b b in the sides, so as to allow its being raised or lowered, and nuts on the bolts screwing against the sides. By these simple arrangements receivers set in new streets, and which are fixed as near the grade as possible at that time, can be made in a few minutes to conform to a new grade when the street is paved.A With the old receivers, when a new grade was established, if below or above, the conf nection with the sewer had to be broken and the receiver raised or lowered at considerable expense. My telescopic arrangement will avoid trouble `or expense, as the nuts will only have to be unscrewed and the top part A raised or lowered, and the nuts again screwed tight. (See Figs. 1 and 3.) When the top part of the receiver is raised, a wedge is put in the space between the two receivers at each corner andthe rest of the space lled in with cement to keep out the 'street dirt or concrete.

The back t ofthe receiver is made to run at a slight slant from the top to a point i nearly opposite the end of the gate C, then giving a sharp curve 11'. from thence to the bottom, and from thencea fiat curve 45 from that point up to the outlet k into the sewer S. This leaves only a narrow space p be-- 'tween the bottom of the trap-door C and the wall z', thus giving greater force to the Water,

and which is sufficient to supply the outlet into the sewer.

The trap-door Gis set at an angle, as shown, on side pieces gy g, cast on the inside walls of the part A and so as to carry the water fallingthrough the grates from the street With space p between the end of the trap and back of the receiver to passthe water and forcing the sand and sediment out of the stenchtrap and bowl thereof into the sewer, which I consider a great and important improvement on all other street-receivers. (See Figs. l and The gate or trap C has inclined flanges e e (see Figs. 1, 3, `5, and 6) on the top near the edge, and round lugs h project from the inside of the receiverwall A', so that these in- .clines will strike against their under side andforce the gate tightly against the side force to the part 1l', and leaving only the together, the upper section A adapted to be having the inolines g g, and lugs h h, the gate raised and lowered and held in position ac- C, constructed with inclined angesee, as and oording to the grade of the street, substanfor the purpose specified.

tially as hereinbefore fully set forth. In testimony WhereofI affix my signature in 5 2. street receiver constructed in two seopresence of two witnesses.
